The former imperial capital of Hue has so much to offer that the two days I spent visiting turned out to be insufficient. I was most impressed by the Citadel, entered on the UNESCO list, from the beginning of the 19th century. The Purple Forbidden City within it was strangely similar to the one in Beijing. The cruise on the Perfume River was also an unforgettable experience, especially when I realized that I was the only passenger of a large ship.
